+                <para>The <filename>/etc/timezone</filename> file
+                configures the system-wide time zone of the local
+                system that is used by applications for presentation
+                to the user. It should contain a single
+                newline-terminated line consisting of a time zone
+                identifier such as
+                <literal>Europe/Berlin</literal>. The file
+                <filename>/etc/localtime</filename> corresponds with
+                <filename>/etc/timezone</filename> and contains the
+                binary time zone data for the time zone. These files
+                should always be changed simultaneously and kept in
+                sync.</para>
+
+                <para>The time zone may be overridden for individual
+                programs by using the TZ environment variable. See
